사용자가 기본 설정을 선택할 수 있도록 드롭 다운 메뉴가있는 대화 상자를 표시하기 위해 사용자 정의 기본 설정을 만들려고합니다.사용자 기본 설정을 설정하는 데있어서 팽창 예외가 발생했습니다.
preferences.xml로는
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<PreferenceCategory
android:key="notification_settings"
android:title="@string/notifications">
<CheckBoxPreference
android:key="pref_send_notification"
android:title="@string/pref_switch_notification"
android:summary="@string/pref_switch_notification"
android:defaultValue="true" />
<ListPreference
android:key="updates_interval"
android:title="Updates interval"
android:summary="Define how often updates will be performed"
android:defaultValue="1000"
android:entries="@array/updateInterval"
android:entryValues="@array/updateIntervalValues"
android:dependency="perform_updates"
/>
<DialogPreference.distancePreference
android:dependency="pref_sync"
android:key="pref_indicate_proximity"
android:title="@string/pref_proximity"
android:dialogTitle="@string/pref_proximity"
android:entries="@array/category_names"
android:entryValues="@array/category_names"
android:defaultValue="@string/pref_proximity" />
</PreferenceCategory>
</PreferenceScreen>
이 내 거리 환경에 대한 코드입니다 :
package com.example.makemyday;
import android.content.Context;
import android.content.DialogInterface;
import android.content.SharedPreferences;
import android.content.SharedPreferences.Editor;
import android.preference.DialogPreference;
import android.util.AttributeSet;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.LinearLayout;
import android.widget.Spinner;
public class distancePreference extends DialogPreference {
private Context context;
private Spinner categories;
private ArrayAdapter<CharSequence> adapter;
public distancePreference(Context context, AttributeSet attrs) {
super(context, attrs);
this.context = context;
setPersistent(false);
setDialogLayoutResource(R.layout.preference_distance);
}
@Override
protected void onBindDialogView(View view) {
categories = (Spinner) view.findViewById(R.id.category_preference);
adapter = ArrayAdapter.createFromResource(context, R.array.category_names, android.R.layout.simple_spinner_dropdown_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); //simple_spinner_dropdown_item simple_spinner_item
categories.setAdapter(adapter);
categories.setSelection(0);
super.onBindDialogView(view);
}
@Override
public void onDismiss(DialogInterface dialog) {
LayoutInflater inflater = LayoutInflater.from(context);
LinearLayout linearLayout = (LinearLayout) inflater.inflate(R.layout.preference_distance , null);
linearLayout.removeView(categories);
super.onDismiss(dialog);
}
@Override
protected void onDialogClosed(boolean positiveResult) {
super.onDialogClosed(positiveResult);
if (positiveResult) {
SharedPreferences.Editor editor = getEditor();
editor.putString(getKey() + ".type", categories.getSelectedItem().toString());
editor.commit();
}
}
}
UserSettingsActivity :
package com.example.makemyday;
import android.content.Intent;
import android.os.Bundle;
import android.preference.PreferenceActivity;
import android.preference.PreferenceFragment;
import android.view.Menu;
import android.view.MenuItem;
public class UserSettingsActivity extends PreferenceActivity{
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getFragmentManager().beginTransaction().replace(android.R.id.content, new UserPreferenceFragment()).commit();
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
menu.add(Menu.NONE, 0, 0, "Show current settings");
return super.onCreateOptionsMenu(menu);
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case 0:
startActivity(new Intent(this, MainActivity.class));
return true;
}
return false;
}
public static class UserPreferenceFragment extends PreferenceFragment
{
@Override
public void onCreate(final Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.preferences);
}
}
}
내가 코드를 실행하고 설정을 클릭합니다 I 다음 오류가 발생합니다.
